Class instance variables aren't inherited and the attr_accessors would 
have to be pretty niftily implemented to serve the same purpose as 
@@vars do now.

I've seen lots of threads on how to do it with attr, and maybe I've 
misunderstood something but I can't help but think that:
  a) they don't cover all the uses of @@vars
  b) those rather mindbending implementations that did come close, 
reeked of overhead and really just makes a slower, syntactic sugar 
version of @@vars.

IMHO.
